bounce

彰化縣二水鄉源泉國小

In this PE class, each student has to bounce a ball on the ground while he or she runs across the basketball court. 

在這班的體育課，每個學生都邊拍球邊在籃球場上來回跑。

The kids have to use the right amount of strength when they bounce the balls so they can control them while they run. 

小朋友要用適當的力道拍球以便能在跑步時還能控制球。
